Oh, I should have done what Andrew suggests before sending my email... op2.init() parameters["coffee"]["O2"] = False seems to fix at least part of my problem :-) Sorry for the noise, Eike -- Dr Eike Hermann Mueller Research Associate (PostDoc) Department of Mathematical Sciences University of Bath Bath BA2 7AY, United Kingdom +44 1225 38 5803 e.mueller@bath.ac.uk http://people.bath.ac.uk/em459/

Ugh, one of the recent changes we made was to turn on COFFEE's optimisations by default. Unfortunately, this has led to some teething problems.
I assume that all components -- COFFEE, Firedrake, PyOP2, FFC, UFL, and FIAT -- are up to date, and that you're running with a clean cache (from the Firedrake base directory, run "./scripts/firedrake-clean").
If the problem persists, as a short-term workaround, can you add
op2.init() parameters["coffee"]["O2"] = False
to the start of your file, just after the imports? This will result in sub-optimal performance during the assembly stage, so isn't ideal in the long-term.
Fabio, our resident barista, will have some fixes after the new year, I'm sure.

I very recently updated firedrake, pyop2 and installed coffee, but since then none of my codes include nonlinear solvers don’t work (they used to work fine before the update).
I even tried to run the burgers.py code from the demo and even that diverges.
I get something like:
